Problem to have acces to the libmpv in MacOs

[gabrielzschmitz (Gabriel dos Santos Schmitz)]

Can't really include the mpv library at any .c file (even adding the +libmpv variant)! Here's a real exemple:

$ sudo make install
cc -std=c99 -Wall -Wextra -pedantic -Wunused-result -Wno-unused-variable -Os -D_POSIX_C_SOURCE -DTOMATONOISE=\"/usr/local/bin/tomatonoise\" -DLOGPREFIX=\".local/share/tomato\" -DLOGFILE=\".local/share/tomato/tomato.log\" -DTMPFILE=\".local/share/tomato/tmp.log\" -DTIMERFILE=\".local/share/tomato/time.log\" -DNOTEPADFILE=\".local/share/tomato/notepad.log\" -I/usr/local/include -L/usr/local/lib  tomatonoise.c  `pkg-config --libs ncursesw mpv` -o tomatonoise
tomatonoise.c:1:10: fatal error: 'mpv/client.h' file not found
#include <mpv/client.h>
         ^~~~~~~~~~~~~~
